Failing that, MSR seem to have a huge choice on weight and price for you.
it depends on your budget, that bat looks as if it needs a new handle and some glueing - so likely to be about £30-40 after postage.
Personally I don't think you will get value from that repair in this case. I think a new bat would provide you with better value.
Moving from 2lbs10-12 to 2lbs 7 is a big shift - i think you may be better off going for a 2lbs 9 bat - but just my thoughts, the change in weight and timing will take a period, but hopefully not too long, get in the nets.
